ABSTRACT:
A recording element for a matrix printer having an armature which is capable of movement relative to a casing under spring action by means of electric energization and to which a recording stylus is secured. The restoring spring surrounding the stylus is centered in the element in that its two end parts each comprise a plurality of closely wound turns. The spring part intermediate the end parts provides the spring action. Thus wear of the spring and the stylus due to rubbing contact is avoided.
